Greek: κύριος (kurios, G2962), generic "master/sir" through to fully divine "Lord" Hebrew background: אֲדֹנָי (Adonai) "Lord" used as substitute for YHWH (H3068) in reverent Jewish reading practice. The LXX consistently renders YHWH as κύριος, so NT writers quoting OT-YHWH passages and applying them to Jesus do so through the kurios-bridge.
Semantic range, three levels of meaning
The Greek κύριος runs from polite to divine:
| Level | Sense | NT example |
|---|---|---|
| 1 | Polite address "sir" | Samaritan woman to Jesus: "Sir, give me this water" John 4:15 |
| 2 | Master / owner | Master of a household or estate; "no servant can serve two masters" Luke 16:13 |
| 3 | Divine Lord | "the Kingdom of our Lord and of his Christ" Revelation 11:15 (citing OT YHWH passages) |
The progression in early disciple usage from level 1 to level 3 across the Gospels is part of the narrative arc, what Jesus's followers call him hardens into divine acclamation over time, culminating in Thomas's "My Lord and my God" at John 20:28.

Theological framing
Kurios-as-divine-name, Paul's letters and Hebrews repeatedly apply OT-YHWH passages to Jesus via the LXX-kurios bridge. This is the strongest NT evidence for high Christology: the NT writers identify Jesus with the OT God of Israel without abolishing monotheism.
Confessional core formula, "Jesus is Lord" (Romans 10:9; 1 Corinthians 12:3; Philippians 2:11) is the most basic NT confession. Likely the earliest baptismal formula.
Threefold-office connection, Lord is the active-rule dimension of the kingly office (cross-link).
Pneumatological connection, 2 Corinthians 3 identifies "the Lord" in context with "the Spirit"; Trinitarian readings handle this as the Lord-Spirit-Father shared divine identity, not as person-confusion.
